GALVANIC BATTERY.

Specification of Letters Patent.

atented Sept. 23, 11913..

Application tiled August 9, 1912. Serial No. 714,218.

To all 'whom fit may concern.'

Be it known that I, JOSEPH IIAior-r, citizen of the United States ofAmerica, resid ing at htuslmgee, in the county of Muskogee and State ofOklahoma, have invented certain new and useful Improvements in GalvanicBatteries, of which the following is a specification.

This invention relates to certain new and useful improvements ingalvanic batteries, the object being to provide a battery which isexceedingly simple and cheap in construction, and one which is verycompact in form; the electrodes and electrolyte being contained within avessel forming the positive electrode.

Another object of my invention is to provide a battery in which anelectrolyte is used, composed of a number of ingredients which areexceedingly cheap, whereby the cost of the battery is reduced and at thesame time the life of the same is greatly in creased.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

In the drawings-Figure l, is a vertical transverse section through agalvanic battery constructed in accordance with my invention; Fig. 2, isa horizontal section taken on the line 2-2 of Fig. l; Fig. 3, is ahorizontal section taken on the line 3-3 of Fig. 1; Fig. 4, is a detailvertical enlarged section showing the binding post and manner ofconnecting the same to the negative electrode and the cover of the jar;and Fig. 5, is a vertical transverse sect-ion through a modified form ofbattery.

In carrying out my improved invention, I employ a cylindrical vessel orcontainer l, preferably formed of iron of medium hardness, forming thepositive electrode, said jar having its outer face coated with anysuitable insulating material 2 which is also extended into the interiorat the upper portion thereof, as shown at 3, said portion having acoating of paramn 4t. The upper portion of the jar or electrode 1, isprovided lwith exterior threads 5 overwhich are arranged the interiorlythreaded portions 6 of a metal cover 7, the inner and the outer facebeing covered by insulating material 8, and the inner face thereof isalso provided with a paraffin coating 9; Frein the above description, itwill be seen that I have pro vided a cylindrical positive electrodewhich forms a container for the electrolyte, as will be hereinafterfully described. Arranged in one of the walls of the cylindricalelectrede 1 is a binding post 10 which is preferably provided with aplug-shaped head 11, as clearly shown in Fig. 1, said binding postextending through the insulation, as clearly shown.

rtrranged within the electrode 1 is a starshaped insulating plate, 12,the points of which are adapted to engage the inner wall of theelectrode 1 and said star-shaped plate is provided with a central recess13, in which is adapted to be seated the negative electrode 1 4-, whichis cylindrical in form, and is formed of carbon of medium softness, andof such size that an annular chamber will be formed in the `jar orelectrode. '.lhe electrode lt is provided with a solid head 15,which isadapted to be seated in a circular recess in an insulating plate 1Gconstructed in substantially the saine manner as the plate l2, and saidinsulating plates 12 and 1G are preferably formed of glass, and areprovided with corrugated faces 17, adapted to contact with the bottom ofthe j a r and the paratlin inner face of the cap thereof, re`spectively. The plates are provided with central openings, as shown at18, and extending through the central opening of the plate .16, is abinding post .18 arranged within the bore forn'ied in the head 15, ofthe negative electrode 14, the head of the post 1S being seated in arecess as shown at 19. The headof theelectrode llt is provided with acap of paratlin 21 which doubly insulates the same and the cylindricalncgative electrode is provided with longitudinally oppositely disposedslots Q9. in order to allow a free circulation of the electrolyte orexciting Afluid within the container so as to expose the inner and outerfaces of the cylindrical electrode to the action of the exciting fluid.

The cap ot the jar 1 is provided with a centrall opening through whichextends an insulating nipple 23 mounted upon the landing post andsecured in position by a nut Qit carried by the binding post, which alsosecures the cap 21 on the head oit the electrode. To thoroughly protectthe binding post in order to obtain proper insulation between thepositive and negative electrodes, 110

lindrieal electrode and a cylindrical carbon electrode arrangedconeentrically, insulating supporting plates for centering the carbonelectrode Within the metal electrode, each plate having a corrugatedface, and binding posts carried by the respective electrodes andinsulated from the container as set forth.

7. A galvanic battery, comprising a positive electrode in the form of acontainer having a detachable cap, said cap and container having aninsulated outer face, star-shaped plates arranged Within said containerand cap having recesses, a negative electrode arranged within therecesses of said plates, and means for insulating said negativeelectrode from the positivo electrode.

In testimony whereof I alix my signature in presence oi two witnesses.
